Ukrainian President Volodymyr Zelenskiy said on Saturday that the end of the more than 2-1/2-year-old war with Russia depended on the "resolve" of Kyiv's Western allies in providing needed weaponry and permission to use it.

Strikes on weapons arsenals are crucial to weaken Moscow’s overwhelming superiority in battlefield firepower, analysts said.
